Embodiment Construction

[0038] like figure 1 As shown, a "communication-communication control" numerical control HID driving method and its driver, the driver consists of an embedded controller 1, an EMI and an input filter circuit 2, a "communication-communication control" drive module 3, and an AC sine output The filter circuit 4, the current / voltage sampling feedback circuit 5, the high-voltage trigger drive module 6, the communication control interface circuit 7, the HID light bulb 8 and the input AC power supply 9 are composed.

[0039]The EMI and input filtering circuit 2 filters out the radio frequency and electromagnetic interference input by the input AC power supply 9, and at the same time, prevents the radio frequency and electromagnetic interference derived from the driver of the present invention from entering the external input power supply, thereby playing a two-way isolation role. The AC power through EM1 and the input filter circuit 2 is output to the embedded controller 1 one way, a...

Abstract

The invention relates to an 'AC-AC (alternating current) regulation and control' based numerical-control HID (high intensity discharge) driving method and a driver applying the same. The numerical-control HID driving method is implemented by direct AC-to-AC power switching. In the numerical-control HID driving method, an embedded controller and an 'AC-AC regulation and control' driving module are used as the core which is connected with various circuits, input sinusoidal AC is subjected to AC modulation directly, a constant-power sinusoidal AC power source meeting requirements for numerical-control HID driving is output, and various lighting functions and control protecting functions under the numerical-control HID driving are realized. The driver is a circuit device applying the numerical-control HID driving method, and a circuit of the driver comprises an EMI (electromagnetic interference) and input filter circuit 2, an AC sinusoidal output filter circuit 4, a current and voltage sampling feedback circuit 5, a high-voltage trigger driving module 6, a communication control interface circuit 7, an HID bulb 8 and an input AC power source 9. The driver is characterized by further comprising the embedded controller 1 and the AC-AC regulation and control driving module 3.

Description

technical field [0001] The invention relates to a "communication-communication control" numerical control HID drive (including step-down drive, boost drive and step-down boost drive) method and its driver, belonging to the field of electrical lighting, which is a high-voltage gas discharge Light (referred to as HID) important accessories of the new generation. The invention is suitable for HIDs with different tube voltages such as high-pressure sodium lamps, metal halide lamps, high-pressure mercury lamps, and dysprosium lamps. It has a wide range of applications, including small power spotlights, counter lights, low beam decorative lights, spotlights, human power stage lights, street lights, squares, stations, docks, stadium lighting, and performing arts venues, restaurants, cars, HID driver for marine lighting. Background technique [0002] 1. HID light source and ballast [0003] HID is currently the main light source for high-power lighting. Due to its advantages such...
